What is nuchal translucency? Nuchal translucency (NT) is a collection of fluid under the skin at the back of a baby's neck. The nuchal translucency scan measures the thickness of this fluid to assess the risk of Down's syndrome. It can be measured using ultrasound. If the scan reveals that there is more fluid than usual, it could be a sign of Down's syndrome. Another sign of Down's syndrome is the shape of the baby's nasal bone.
